There are small single family houses for sale in Milwaukee under $100,000. I’ve brought this up on the Milwaukee Reddit and the people on there seem to believe the only worthwhile places to live are in Wauwatosa, Bay View, Shorewood, etc. But not in Milwaukee.
A “nice family” doesn’t have to be white. A nice family can be of any race or color.
There’s no “bribes to the city”. The city already offers developers the ability to buy blighted properties for $5,000 each. There’s deed restrictions for selling it and development restrictions on needing to get work done in a certain timeframe.
Homeowners probably won’t be able to do this alone. It would take a combination of the city to provide the properties and subsidies for renovation, developers to renovate them, and homeowners to purchases in that area.
